MKB OH20 Max Wireless Headphone

Your everyday marathon headphone. The mkb oh20 max is built around one job: keeping your music alive for days on a single charge. The verified figures are the whole pitch — an 800mAh battery, up to 120 hours of wireless playtime, and a full recharge in about 2 hours, all per manufacturer. For commuters, students, and workday callers, the this headphone is the headphone you stop thinking about charging.

One identity note before the details: this listing is the MKB-branded OH20 Max — the branding most BD stores stock — and it is a separate listing from the MK3 (no-brand) OH20 Max also listed on this store. Same white-label OH20 family, different brand token, different listing; this page describes the mkb oh20 max only. Nothing below is shared with, or copied from, the other variant’s page.

What follows is the full walkthrough: the 120-hour battery, the fold-flat design, the Bluetooth 5.3 connection, the comfort and hands-free calls, and the honest spec table. Every figure is taken from the verified research notes — no driver-size number is claimed, because the notes do not give one, and nothing is invented.

Up to 120 Hours of Playtime

The card above states the headline in five words: “Up to 120 Hours of Playtime,” with the subline “800mAh · ~2h charge.” The 800mAh cell is the biggest battery in this price class of wireless headphones, and the mkb oh20 max turns it into up to 120 hours of playback on one charge — the manufacturer’s rating, footnoted honestly as “*Per manufacturer.” Charge it once on Sunday and the this headphone keeps playing through the entire week: commute playlists, workday calls, evening podcasts, all without a second thought about the battery.

The honest read: 120 hours is the rated figure under the manufacturer’s conditions; your real mileage varies with volume, how far you roam from your phone, and how many calls you take. But even at a fraction of the rated number, the mkb oh20 max outlasts everything around it — this is the never-charge-again emotion the model is famous for. A full recharge takes about 2 hours, so even when the battery finally runs low, the this headphone is back to full during a morning’s work.

Folds for the Bag

The card’s promise is “Folds for the Bag,” with the subline “Compact foldable design for travel.” The mkb oh20 max is a foldable over-ear headphone — the earcups fold flat so the whole thing slips into a backpack or carry-on instead of hanging off your neck all day. For the daily metro commute, the campus walk, or a road trip, the this headphone packs like it was made for the bag.

Portability is half the point of this model. The matte-black build is compact and understated, with soft black ear cushions and a padded headband that fold away neatly with the cups. The mkb oh20 max is the headphone that travels with you instead of being left on the desk — folds flat, slips in, plays for days.

Stable BT 5.3 Wireless

The card calls it “Stable BT 5.3 Wireless” — “Fast pairing · 10m range.” Bluetooth 5.3 pairs quickly and holds a steady connection up to 10 meters, so the mkb oh20 max stays linked while your phone sits in your bag or on the desk. Walk to the kitchen, cross the room, reach for the bus handle — the this headphone doesn’t drop.

The 10-meter range covers real life: phone in the pocket during a commute, laptop on the desk during a work call, tablet on the nightstand while you tidy the room. The mkb oh20 max works with phones, tablets, and laptops — any Bluetooth source — with no wires to snag and no dongles to lose.

OH20 Max — Key Specs

The infographic above is the whole pitch in five chips: BT 5.3, 800mAh, 120h, 10m, foldable. That is the mkb oh20 max in one glance — the wireless version, the battery size, the rated playtime, the range, and the fold-flat design. It is footnoted “*Per manufacturer. Illustrative reconstruction,” and the copy says the same: the visual is a summary, the figures are verified.

What the card deliberately does NOT claim matters as much as what it does. The research notes give no driver size in millimetres, so this page claims none. There is no ANC and no water-resistance rating in the notes, so neither is claimed anywhere on this page. The mkb oh20 max is sold on what it provably is: a 120-hour foldable Bluetooth 5.3 over-ear with hands-free calls — and that is plenty.

Comfort + Calls

The card’s headline is “Comfort + Calls” — “Padded cushions · built-in mic.” The mkb oh20 max ships with soft padded oval ear cushions and an adjustable headband that spreads the weight, so hours of wear stay pleasant. The this headphone is the headphone you forget you’re wearing — through the commute, the workday, the long trip.

The built-in microphone handles hands-free calls: take the call while you multitask, stay on the work meeting while your hands stay on the keyboard. For students on online classes and commuters catching up with family, the mkb oh20 max is a daily-driver communicator, not just a music player.

Inside the MKB OH20 Max

The x-ray render above is an illustrative reconstruction of the mkb oh20 max’s internals — not a teardown photo — with leader-line callouts marking the parts that matter: the driver, the 800mAh battery cell, and the Bluetooth board. The image’s own footnote says it honestly (“*per manufacturer · Illustrative reconstruction”), and the copy says the same: this is a visualization of the architecture.

The battery is the hero part. Most of what makes the mkb oh20 max an over-ear instead of an earbud is that 800mAh cell — the hardware reason the rated playtime stretches to 120 hours. Big battery, small footprint, as the card says: the this headphone packs marathon power into a fold-flat frame.

Folds Flat, Built to Last

The hinge close-up above — “Folds Flat, Built to Last” — shows the part of the mkb oh20 max that does the daily work of folding. The foldable joints are the most-used moving part on this headphone, folded and unfolded every commute, every trip, every bag. The x-ray is an illustrative reconstruction, footnoted as such, but the design idea is real: a fold mechanism made to survive the daily fold.

Treat it like the rest of the mkb oh20 max — the matte-black frame, the padded headband, the soft cushions — and it stays a daily driver for the long run. Folding flat also protects the earcups in transit: less bulk in the bag means less banging around. The this headphone is built for the bag and the routine, not the shelf.

Your Daily Driver

The promo hero above says it plainly: “Your Daily Driver,” with the “120H Battery” chip and the subline “120h battery. Folds flat.” That is the mkb oh20 max’s whole value pitch in four words — the headphone that handles the commute, the classes, the work calls, and the weekend trip on one charge.

Who it is for: students who need a headphone that survives campus days, travelers who need one charge to cover the whole trip, commuters who need hands-free calls in traffic. The mkb oh20 max is the budget wireless over-ear that keeps up with a full day — then another, then another.

Commute-Proof

The final card is the mkb oh20 max in its natural habitat: “Commute-Proof” — “BT 5.3 · hands-free calls · 10m range.” A man wearing the this headphone through a golden-hour market street, phone in pocket, music on, calls coming through hands-free. This is the use case the model was designed for.

Dhaka commutes are long and loud; the mkb oh20 max answers with 120 hours of battery you never think about, Bluetooth 5.3 that holds through the crowd, and a mic that keeps you on the call. Commute-proof is not a slogan here — it is the spec sheet doing its job.

Specifications

All figures are taken from the verified research notes for the mkb oh20 max — no driver-size figure is claimed anywhere, because the notes do not give one; no ANC, water resistance, or official-distributor status is claimed either.

Does it have ANC or water resistance?
